INSTRUMENT-HOLDING DEVICE.

Application filed July 24,

To all whomz't may concern:

Be it known that I, VILLIAM R. Horr- MANN, a citizen of the United States, residing at Kansas City, in the county of J ackson and State of Missouri, have invented a certain new and useful Improvement in Instrument-I-Iolding Devices, of which the following is a specification.

My invention relates to improvements in instrument holding devices, adapted to hold such instruments as pins orneedles.

One of the objects of my invention is to provide a device of the kind described, which is simple, cheap, durable, not liable to'get out of order, which permits easy insertion or extraction of the instrument, which will safely hold the instruments and is convenient to use, and which may be used in association with any ordinary thread spool.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates my invention,

Fig. 1 is a side elevation of the preferred embodiment of my improved instrument holding device.

Fig. 2 is a vertical section on the line 22 of Fig. 1.

Fig. 3 is a cross section on the line 3-3 of Fig. 1.

Fig. 4 is a perspective view of the instrument container shown in Figs. 1, 2 and 3.

Fig. 5 is a side View, partly in elevation and partly in vertical section of a modification of my instrument holding device.

Fig. 6 is a perspective view of the instrument containing parts shown in Fig. 5.

Similar reference characters designate similar parts in the different views.

In the form of container shown in Figs. 1 to 4, the container comprises a shell having a cylindrical body 1 closed at both ends and provided at one end with a head 2 of larger diameter than the body 1.

The body 1 is provided with a longitudinal slot 3, for the insertion into or removal from the container of instruments,'such as needle-s or pins.

Th body 1 may be of resilient material, such as sheet steel or brass, audit is adapted for insertion into and removal from the hole 4 of an ordinary thread spool 5. To hold the body in the hole 4, the body may be provided with a peripheral projection 6 1923. Serial No. 653,525.

adapted to bear against the inner wall of the spool.

In the operation of the preferred form of my invention, the instruments, such as needles or pins, 7, are placed in the body 1 through the slot 3, after which the body 1 is slipped into the hole of a spool 5, the lat- In the form of my invention shown in Figs. 5 and 6, the instrument container comprises two shells 8 and 9, each having a cylindrical body adapted to be fitted in the hole 4 of a spool 5.

In the operation of this form of my invention, the shell 9 is fitted in one end of the hole 4 and is provided with a head 10 of greater diameter than the hole 4, the head bearing against the adjacent end of the spool.

The shell 8 is provided with a head 11 of greater diameter than the hole 4 and adapted to rest against the adjacent end of the spool. The shell 8 should be of sufficient length for holding the instruments when the shell is removed and disposed open end up. When it is desired to insert instruments into or remove them from the shell 8, the head 11 of the latter and the shell is withdrawn from the spool.

lVhen the instruments are placed in the shell 8, and the latter is inserted in the hole of the spool, at the end opposite the end containing the shell 9, the latter with the shell 8 will safely retain the instruments in the spool.

The spool 5 elfects a double function, that of holding thread and supporting the instrument container and holding the instruments safely therein.

I do not limit my invention to the structures shown and described, as many modifications within the scope of the appended claim, maybe made without departing from the spirit of my invention.

is gripped What I claim is An instrument holding device comprising a spool and a shell adapted to contain instrun'ients, the shell having a resilient body, the latter having a peripheral projection adapted to engage the inner Wall of the spool, said body being insertihle into the hole of the spool, the shell having a longitudinal slot for the insertion and removal of instruments, the shell having closed ends 10 and a head at one end of greater diameter than the body of the shell.

In testimony whereof I have signed my name to this specification.

WILLIAM R. HOFFMANN.
